Green Bean Onion Casserole Recipes

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Place green beans and soup in a large microwave-safe bowl. Mix well and heat in the microwave on HIGH until warm (3 to 5 minutes). Stir in 1/2 cup of cheese and heat mixture for another 2 to 3 minutes. Transfer green bean mixture to a casserole dish and sprinkle with French fried onions and remaining cheese.
• Bake in a preheated 350 degrees F (175 degrees C) oven until the cheese melts and the onions just begin to brown.

Steps:

• Prepare the casserole: Preheat the oven to 350 degrees F. Bring a large pot of salted water to a boil. Add the green beans and pearl onions and cook until the beans are bright green, 2 to 3 minutes. Drain the vegetables, then plunge into an ice bath to stop the cooking. Drain, then remove the skins from the pearl onions.
• Combine the olive oil and butter in a large skillet over medium heat. Add the garlic and shallot and cook, stirring, until the shallot is caramelized, about 5 minutes. Add the bay leaves, then the mushrooms. Stir to combine, then add the thyme and season with salt and pepper. Sprinkle the mixture with the flour to tighten it up. Add the milk and boil 3 minutes to thicken; remove the bay leaves.
• Place the green beans and pearl onions in a 3-quart casserole dish. Pour the "mushroom soup" over the vegetables and toss to make sure they are well coated. Transfer to the oven and bake 30 minutes.
• Make the topping: Heat about 2 inches of vegetable oil in a large pot or Dutch oven until a deep-fry thermometer registers 360 degrees F. Toss the shallots in a bowl with enough flour to lightly coat. Working in batches, fry the shallots until golden brown and crisp, about 3 minutes. Using a slotted spoon, remove to paper towels to drain; season lightly with salt. Scatter over the casserole before serving.

Steps:

• Preheat the oven to 475 degrees F.
• Combine the onions, flour, panko and salt in a large mixing bowl and toss to combine. Coat a sheet pan with nonstick cooking spray and evenly spread the onions on the pan. Place the pan on the middle rack of the oven and bake until golden brown, approximately 30 minutes. Toss the onions 2 to 3 times during cooking. Once done, remove from the oven and set aside until ready to use. Turn the oven down to 400 degrees F.
• While the onions are cooking, prepare the beans. Bring a gallon of water and 2 tablespoons of salt to a boil in an 8-quart saucepan. Add the beans and blanch for 5 minutes. Drain in a colander and immediately plunge the beans into a large bowl of ice water to stop the cooking. Drain and set aside.
• Melt the butter in a 12-inch cast iron skillet set over medium-high heat. Add the mushrooms, 1 teaspoon salt and pepper and cook, stirring occasionally, until the mushrooms begin to give up some of their liquid, approximately 4 to 5 minutes. Add the garlic and nutmeg and continue to cook for another 1 to 2 minutes. Sprinkle the flour over the mixture and stir to combine. Cook for 1 minute. Add the broth and simmer for 1 minute. Decrease the heat to medium-low and add the half-and-half. Cook until the mixture thickens, stirring occasionally, approximately 6 to 8 minutes.
• Remove from the heat and stir in 1/4 of the onions and all of the green beans. Top with the remaining onions. Place into the oven and bake until bubbly, approximately 15 minutes. Remove and serve immediately.

Steps:

• Preheat oven to 375 degrees F (190 degrees C). Grease a 9x13 inch casserole dish.
• Heat 2 tablespoons of butter in a large skillet over medium heat. Stir the onions into the pan; cook and stir until very soft and golden brown, about 15 minutes. Stir in sherry vinegar. Transfer to a small bowl, and reserve.
• In the same skillet, melt 2 more tablespoons butter. Whisk in 2 tablespoons flour. Stirring constantly, cook over medium heat until the flour smells like baked pie crust, about 3 minutes. Slowly whisk in milk, about 1/2 cup at a time, then whisk in nutmeg, cayenne pepper, and thyme. Bring to simmer, and cook until thickened, whisking constantly, 3 more minutes. Transfer to a bowl and reserve.
• Melt remaining 2 tablespoons butter in clean skillet; stir in panko until all crumbs are coated; reserve.
• Bring a large saucepan of salted water to a boil over medium heat, and boil beans until bright green and crisp but not raw tasting, 3 to 4 minutes. Drain very well.
• Spoon half of the caramelized onions into the prepared casserole dish; top with green beans. Season with salt and black pepper. Spread reserved white sauce over the green beans; sprinkle with half of the Gruyere cheese. Top with the rest of the onions, and use the back of a spoon to push onions down into sauce and cheese. Top with the buttered panko crumbs, the remaining Gruyere, and Parmesan cheese.
• Bake in the preheated oven until hot throughout and lightly browned, about 30 minutes. Let sit 10 minutes before serving.

Steps:

• Cook the green beans: In a large pot, bring 6 quarts of water to a boil. Salt the water generously; it should taste like sea water.
• Prepare an ice bath: Fill a large bowl halfway with ice and add some cold water. Place a colander squarely inside the ice bath; the colander will keep you from having to pick the beans out from amongst the ice cubes. Plunge the green beans into the water and cook 2 to 3 minutes. When the beans are cooked, remove them from the hot water with a strainer and transfer them to the colander inside the ice bath. Use a spoon to "swirl" the beans around in the ice bath so they cool quickly. Drain.
• Make the mushroom base: In a 10-inch cast-iron skillet, melt the butter and add the mushrooms. Season with salt and add the mustard and cayenne. Cook until the mushrooms give off most of their liquid, 5 to 8 minutes. Whisk the garlic and flour into the mushrooms. Cook the flour 1 to 2 minutes, stirring constantly so it doesn't stick or burn, and then add the chicken stock. Bring to a simmer and reduce 1 to 2 minutes. Stir in the cream and sour cream and simmer gently. Continue cooking over low heat until the mixture thickens, 5 to 8 minutes. Set aside.
• Preheat the oven to 350 degrees F.
• Fry the onions: Pour the oil into a medium frying pan. Heat to 350 degrees F.
• In a medium bowl, combine the flour and cayenne. Toss the onion rounds in the flour and "shake" off excess by shaking the rounds in a strainer once they have been breaded. Test the oil by dropping in a few slices; they should rise to the surface and fry gradually.
• Prepare a baking sheet fitted with a kitchen towel. Drop a small batch of the onions into the oil and gently "swirl" with a slotted spoon in the oil as they fry; this will help them fry more evenly on all sides. Fry until golden brown, 1 to 2 minutes. Remove from the oil and spread on the baking sheet. Season immediately with salt.
• Bake and serve: When ready to serve, stir the green beans into the mushrooms. Simmer on the stove over low heat for 2 to 3 minutes so the beans and sauce meld together. Add more cream and a splash water if the sauce is too thick. Transfer the skillet to the oven for 8 to 10 minutes to finish heating it and to give the casserole that "baked" effect. Remove from the oven and top with the fried onions. Serve immediately.

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Melt 2 tablespoons butter in a large skillet over medium heat. Stir in flour until smooth, and cook for one minute. Stir in the salt, sugar, onion, and sour cream. Add green beans, and stir to coat.
• Transfer the mixture to a 2 1/2 quart casserole dish. Spread shredded cheese over the top. In a small bowl, toss together cracker crumbs and remaining butter, and sprinkle over the cheese.
• Bake for 30 minutes in the preheated oven, or until the top is golden and cheese is bubbly.
